Benefits of technology

"The present invention relates to an elevator system that operates a plurality of elevators with good efficiency without an increase in processing load for elevator control. The invention solves the problem of decreased operation efficiency during peak busy hours by controlling the operation of elevators based on the traffic condition in a building. The invention includes a car call registration device, a group supervisory controller, assigned car information means, a building specification data storage section, a specially-assigned floor judgment section, a traffic condition judgment section, and an assignment control section. The invention allows for the efficient operation of elevators without increasing processing load for elevator control."

Problems solved by technology

For this reason, if the same group supervisory control is always performed in the above-described building and the like, the operation efficiency may decrease during peak busy hours.

embodiment 1

[0024]FIG. 1 is a block diagram showing an elevator system in Embodiment 1 of the present invention, and FIG. 2 is a flowchart showing operations of the elevator system in Embodiment 1 of the present invention. Incidentally, the configuration and operations of the elevator system shown in FIGS. 1 and 2 are intended for the group supervisory control of a plurality of elevators installed within one and the same building. First, the configuration of the above-described elevator system will be described on the basis of FIG. 1.

[0025]In FIG. 1, reference numeral 1 denotes a car call registration device by use of which an elevator user registers a car call (a destination floor) before riding on a car. When a destination floor is inputted by the operation of a user, this car call registration device 1 outputs a car call registration request to a group supervisory controller 2, which will be described later. The car call registration device 1 is provided with assigned car information means 3...

embodiment 2

[0043]FIG. 3 is a block diagram showing the main part of an elevator system in Embodiment 2 of the present invention, and FIG. 4 is a flowchart showing the operations of the elevator system in Embodiment 2 of the present invention. In FIG. 3, a group supervisory controller 2 is provided with a processing performance judgment section 10 in addition to a building specification data storage section 4, a specially-assigned floor judgment section 5, a traffic condition judgment section 6, and an assignment control section 7. Other points of configuration are the same as in Embodiment 1.

[0044]The processing performance judgment section 10 is means for judging the condition of the processing performance of the group supervisory controller 2 having the assignment control section 7. Specifically, the above-described processing performance judgment section 10 makes a judgment as to whether or not the condition of the processing performance of the group supervisory controller 2 during judgment...

Abstract

An elevator system including a car call registration device by which an elevator user registers a car call before riding on a car and a group supervisory controller with a building specification data storage section in which building specification data including specially-assigned floors is stored. Further, a specially-assigned floor judgment section judges whether a departure floor is a specially-assigned floor when a car call is registered, and a traffic condition judgment section judges the traffic condition of elevators within a building. A car assignment is performed based on the traffic condition judgment section judging by the specially-assigned floor judgment section that the departure floor is a specially-assigned floor, and a car assignment is performed based on a building specification stored in the building specification data storage section when the specially-assigned floor judgment section judges the departure floor is not a specially-assigned floor.

Description

TECHNICAL FIELD[0001]The present invention relates to an elevator system that operates a plurality of elevators with good efficiency.BACKGROUND ART[0002]In a building and the like where there are many elevator users, the group supervisory control of a plurality of elevators installed within one and the same building is performed, whereby the operation efficiency of an elevator system as a whole is improved. In the elevator system that performs such group supervisory control, in general, what is called elevators running neck to neck are eliminated by some method and each elevator is controlled so that the waiting time of users becomes short.[0003]In a large-scale office building and the like, the number of elevator users tends to increase abruptly in specific time zones, such as the clock-in time zone, lunch time zone and clock-out time zone. For this reason, if the same group supervisory control is always performed in the above-described building and the like, the operation efficien...
